Final answer:

Amperage in electrical circuits is calculated by dividing the power in watts by the voltage in volts, using the formula I = P / V.

Step-by-step explanation:

The calculation of amperage (A) in electrical circuits is straightforward; it is derived from the relationship between power (P), voltage (V), and current (I). In accordance with the formula for electric power, P = IV, where P is power in watts, I is current in amperes, and V is voltage in volts. To calculate the current, we rearrange the formula to I = P / V. Therefore, amperage is calculated by dividing watts by volts.

For instance, a car's auxiliary power outlet may deliver a maximum power of 240 watts at a voltage of 12 volts. Using our formula, the maximum current the outlet can provide is I = P / V = 240 W / 12 V, which equals 20 A. This example helps us understand how electric power, measured in watts, relates to current and voltage in practical applications.

In this scenario, the surgeon who walks in and says, "I cannot operate on this boy as he is my son," is revealing that they are the boy's mother. The answer is C) The surgeon is the boy's other father.
This situation is an example of a common assumption that the surgeon is male, which leads to the misconception that the surgeon cannot be the boy's mother. This assumption is based on societal gender roles and expectations. It's important to recognize and challenge these assumptions in order to promote gender equality and eliminate gender biases in various professions, including medicine. By acknowledging that the surgeon can be the boy's mother, we break down stereotypes and encourage inclusivity
